As described above, the server 1 may collect information of the mobile devices 10, and manage the mobile devices 10 for the plurality of groups. The server 1 may also manage or handle a mutual interaction between the at least two groups of the plurality of groups.

Elements of the server 20 may provide information to each other as necessary. In one embodiment, the collecting section 220 may provide the information of the current locations of the mobile devices to the creating section 204, the providing section 208, the identifying section 222, the calculating section 230, the estimating section 232, the detecting section 250, etc.

FIG. 2 shows an example of three groups of the mobile devices 10. In the example, FIG. 2 shows a group A, a group B, and a group C. The group A includes a plurality of mobile devices 10 shown as white circles, and is shown as 100A. One of the mobile devices 10 in the Group A may be the representative mobile device 10′ shown as a black circle. The group B (shown as 100B) and the group C (shown as 100C) may each include the representative mobile device 10′. When the groups communicate with each other, each representative mobile device 10′ represents each group and the representative mobile devices 10′ may transmit and receive messages among each other.

For example, the representative mobile device 10′ in the group A may communicate with the representative mobile device 10′ in the group B as shown in FIG. 2, but the representative mobile device 10′ does not need to communicate with the other mobile devices 10 in the other groups.

The plurality of the groups may form a team. For example, a team may comprise the group A, the group B, and the group C. The system 1 may manage one or more teams, each comprising a plurality of groups of mobile devices 10.

FIG. 3 shows an example operational flow of the system according to an embodiment of the present disclosure. The present embodiment describes an example in which a system, such as the system 1, performs the operations from S110 to S190, as shown in FIG. 3. The system may set the configuration of the session and manage groups of mobile devices during the session by performing the operations S110-S190.

First, at S110, a setting section such as the setting section 202 may set configuration of a session, such as a group policy and/or a registration method to groups.

In one embodiment, the setting section may receive a group policy from a computer of a session initiator. The computer of the session initiator may be one of the plurality of the mobile devices, the server itself, or other computers. In one embodiment, the session initiator may be a host of a trip to the target location.

The group policy may include a definition of a group, existence or non-existence of the representative mobile device, a definition of the representative mobile device, a workflow of transfer of the mobile device between groups (e.g., a definition of a stray mobile device), a workflow of determination of a new representative mobile device at a merger of groups, and a condition to start and/or end the session.

The definition of a group may include information of (a) group IDs, (b) team IDs, (c) representative mobile devices of each group (e.g., existence or non-existence of the representative mobile device, and/or, an authority of the representative mobile device), (d) qualification to join in a team or group (e.g., having a registered names, joining in a certain organization such as a certain company or social networking service (SNS), having a certain relationship such as family, friend, or alumnus with a user of the representative mobile device, located at a location so as to communicate by short distance communication, joining in the same trip, or sharing the same destination), and/or (e) a target/goal of each team/group (e.g., the destination, task, target, etc.).

In one embodiment, the setting section may receive the registration method for joining the session from the computer of the session initiator. In one embodiment, the mobile devices that have been registered in the system can join in a team and group. For example, the registration method may be starting a specific application, and sending the registration information via the application to the server. The setting section may register the mobile devices sending the registration information as participants to the session.

In other examples, the registration method may be registering information of the mobile devices such as phone numbers and/or email addresses. In the example, the setting section may receive information of the plurality of the mobile devices from the computer of the session initiator.

In other examples, the registration method may be collecting information of the mobile devices from a SNS service, a shared calendar service, or the like. In this example, the setting section may collect phone numbers and/or email addresses from a certain community (e.g., a community of participants to a travel) in SNS as participants to the session.

The setting section may store the group policy and/or the registration method to groups in the storage section.

Next, at S130, the system starts the session. For example, the setting section may disclose the registration method set at S110, and collect information of the mobile devices participating to the session.

Next, at S150, the server may determine the participants to the session according to the registration method. For example, the setting section may determine the mobile devices from which information is collected at S130, as the participants.

The server may determine the representative mobile devices for a plurality of groups among the plurality of mobile devices. In one embodiment, the setting section may randomly determine the representative mobile devices, or determine the representative mobile devices based on a nomination from the session initiator or self-nomination. The setting section may provide information of the mobile devices determined as participants, to the representative mobile devices of the plurality of groups.

Next, at S160, the system may create a plurality of groups of the mobile devices. Further details of S160 are explained below.

Next, at S165, a providing section such as the providing section 208 may provide the mobile devices in the group created at S160 with information of the target location. In one embodiment, the providing section may estimate the route from a location of the representative mobile device to the target location and may provide the mobile devices in the group with the route. In one embodiment, the providing section may retrieve information of tourist spots, shops, stores, restaurants, etc. on or near the estimated route, and provide the mobile devices in the group with the retrieved information.

Next, at S170, the system may detect a stray mobile device and may manage movement of the mobile device between the groups. Further details of S170 are explained below.

Next, at S180, the system may manage meeting and merging of at least two groups of mobile devices during the trip to the target location. The operation of S180 may be processed in parallel with the operation of S170. Further details of S180 are explained below.

Next, at S190, the server may determine whether to end the session. For example, a handling section, such as the handing section 210, may determine whether the condition to end the session stipulated in the group policy is met. The handling section may end the session if the decision is positive, and proceed with the operation of S170 if the decision is negative. In one embodiment, the condition to end the session may be that a closing time has arrived, that more than a certain number of mobile devices have arrived at a target location, or the like.

FIG. 4 shows an example operational flow of the system according to an embodiment of the present disclosure. The present embodiment describes an example in which a system, such as the system 1, performs the operations from S210 to S250, as shown in FIG. 4. The system may perform the operation of creating groups, such as S160 in FIG. 3, by performing the operations S210-S250.

At S210, the representative mobile device may transmit an invitation to other mobile devices by short distance communication such as Bluetooth®, infrared communication, etc. Therefore, the representative mobile device may transmit the invitation only to the mobile devices located near the representative mobile device.

Next, at S230, the representative mobile device may receive responses to the invitation from mobile devices via short distance communication or other network types. The representative mobile device may receive the responses including acceptance or rejection to the invitation and the identification information of the mobile devices (e.g., IDs, phone number, or, email address of the mobile devices), and transmit the identification information of the mobile devices to the server.

The representative mobile device may receive a response indicating that the mobile device receiving the invitation has accepted the offer or a response indicating that the mobile device receiving the invitation has rejected the offer.

The representative mobile device may transmit information of the received response from the mobile devices to the server. In one embodiment, the representative mobile device may transmit device IDs of the responding mobile devices to the server.

Next, at S250, a creating section, such as the creating section 204, may create a group of the mobile devices 10 based on the responses received at S230. In one embodiment, the creating section may create a group including the representative mobile device and the mobile devices that have accepted the invitation. In the embodiment, the creating section may update records of the mobile devices of the created group in the device ID list stored in the storing section.

The system may perform the operations of S210-250 for each of the representative mobile devices, and create one or more groups. In one embodiment, the creating section may create groups based on the locations of the mobile devices instead of the operations of S210-250.

In this embodiment, a collecting section, such as the collecting section 220, may collect locations of the mobile devices by receiving information of the current location of the mobile devices from GPS 12. The creating section may then divide the mobile devices into the plurality of groups based on the locations of the mobile devices. For example, the creating section may divide the mobile devices into a certain number of groups such that the total distance between the representative mobile device (or center) of the group and the mobile devices belonging to each group is minimized.

FIG. 5 shows an example of an invitation transmitted at S210. For example, mobile devices located near the representative mobile device and capable of communicating with the representative mobile device via short distance communication may receive an invitation, as shown in FIG. 5. The mobile device receiving the invitation may show a message “Receive an invitation to join the group below” (box 508) on the display screen, and receive a response of either “Accept Offer” or “Reject Offer” from the user. The user of the mobile device may input the response by tapping the “Accept Offer” icon 504 or “Reject Offer” icon 506.

The representative mobile device may transmit the invitation to a team instead of the invitation to a group. In such an embodiment, the representative mobile device may transmit information of the mobile devices accepting the invitation to the server, and the setting section may register such mobile devices as the participants.

FIG. 6 shows an example operational flow of the system according to an embodiment of the present disclosure. The present embodiment describes an example in which a system, such as the system 1, performs the operations from S310 to S395, as shown in FIG. 6. The system may detect a stray mobile device, such as the operation of S170 in FIG. 3, by performing the operations S310-S395.

At S310, a collecting section, such as the collecting section 220, may collect locations of the mobile devices. In one embodiment, each of the plurality of the mobile devices may detect its current location by GPS, and transmit information of the current location to the server. The collecting section of the server may receive the information of the current locations from the plurality of the mobile devices.

Next, at S330, an identifying section such as the identifying section 222 may identify the locations of groups. In one embodiment, the identifying section may calculate a center location of a plurality of mobile devices in a group, and determine the center location as the location of this group. In other embodiment, the identifying section may determine the location of the representative mobile device of a group as the location of this group.

Next, at S350, a detecting section, such as the detecting section 250, may determine a stray mobile device, which strays from the group to which it belongs. In one embodiment, the detecting section may compare a location of each mobile device in a group and a location of the group, and may detect a mobile device that is distant from the location of the group to which it belongs by at least a threshold distance, as the stray mobile device.

In some embodiments, the detecting section may detect a mobile device that is distant from the location of the group for a time longer than a certain duration, as a stray mobile device. In some embodiments, the detecting section may not determine the mobile device(s) as a stray mobile device, if the detecting section finds the mobile device(s) located in a certain location such as a bathroom, a ticket office or the like.

Next, at S360, an informing section, such as the informing section 252, may indicate the location of the group and the location of the stray mobile device(s) to the representative mobile device for each group. In one embodiment, the informing section may transmit the information of the locations of the groups to the representative mobile devices of the groups.

The informing section may also transmit information of identification of the stray mobile device(s) of a group (e.g., name of the user), and the location of the stray mobile device(s) to the mobile devices. Thereby, the system may notify members of the groups, of current locations of the groups and group members that have strayed from the groups, and help the group members to travel in groups.

Next, at S370, a displaying section, such as the displaying section 16 of the mobile devices 10, may display a location of the group to which the mobile device belongs and locations of other groups near the group to which the mobile device belongs. In one embodiment, the displaying section may show a map and the location of the group to which the mobile device belongs on the map on the display screen, and the locations of other groups on the map. If there is a stray mobile device, then the displaying section may display the location(s) of the stray device(s) of the group to which the mobile device belongs.

Next, at S380, the detecting section may determine whether the stray mobile device detected at S350 leaves the group to which the mobile device belongs. In one embodiment, the detecting section may determine that the stray device is distant from the location of the group to which the mobile device belongs by a certain distance, and/or, that the stray device is distant from the location of the group to which the mobile device belongs for a time longer than a certain time. If the detecting section determines that the stray device has left the group, then the detecting section may proceed with S385, and if not, then the detecting section may proceed with S390.

At S385, a changing section, such as the changing section 216, may delete the information of the group from the record of the mobile device in the device ID list, which may be stored in a storing section such as the storing section 206. Thereafter, the mobile device that has left may be treated as a solitary mobile device. The changing section may end the stray mobile device detection.

At S390, the changing section may determine whether an existing solitary mobile device may join a group of the plurality of groups. In one embodiment, the changing section may determine whether the solitary mobile device is within a certain distance from at least one of the locations of the groups. In one embodiment, the changing section may further determine whether the solitary device is eligible to join to the group according to the group policy stored in the storing section. If the decision is positive, then the changing section may proceed with S395, and if negative, then the changing section may end the stray mobile device detection.

At S395, the changing section may add the solitary mobile device to the group. In one embodiment, the changing section may notify a representative mobile device of the group to be joined (e.g., the group nearest to the solitary mobile device) of the solitary mobile device, and receive a response from the representative mobile device. If the response indicates that the group accepts the solitary mobile device, the changing section may add information of the group to the record of the solitary mobile device in the device ID list and may transmit the notification that the solitary mobile device enters the group, to the mobile devices of the group. If the response indicates that the group rejects the solitary mobile device, the changing section may transmit the notification that the group rejects the solitary mobile device, to the solitary mobile device. The changing section may end the stray mobile device detection.

As described above, through the operations of S380-S395, the changing section may dynamically change the mobile devices of at least one group. Through the operations of S380-S395, at least two groups may exchange a mobile device.

FIG. 7 shows an example of a display screen of the mobile devices displaying the groups. The displaying section may show locations of the groups as shown in FIG. 7 in the display screen of the mobile device. In FIG. 7, the display screen may show locations of Group A (704), Group B (706), Group C (708) on the map. Numbers shown in circles of Groups A-C may represent headcounts of Groups A-C. In one embodiment, Group A may include 4 mobile devices (or 4 group members), Group B may include 3 mobile devices, and the group C may include 10 mobile devices.

A group to which one mobile device belongs is distinguishably displayed on the display screen of the one mobile device. For example, a mobile devices belonging to the group A may display Group A by a color, size, brightness, font type, or the like different from other groups. In the example of FIG. 7, the mobile device of Group A displays Group A by a hatched circle, and other Groups by a not-hatched circles. The mobile device may display a plurality of groups with different colors on the display screen.

In addition, a representative mobile device may display its representing group differently from other mobile devices in the group. In one embodiment, the representative mobile device representing Group A may display a representative mark 701 near the circle of Group A, while the other mobile devices in Group A may display the circle of Group A without the representative mark 701. Thereby, the system may notify the users of the representative mobile device (or the leader of Group A) to represent the groups.

A triangular mark 702 may represent a stray mobile device. In one embodiment, mobile devices (or only a representative mobile device) of a group may display the location of the stray mobile device on the map.

FIG. 8 shows an example operational flow of the system according to an embodiment of the present disclosure. The present embodiment describes an example in which a system, such as the system 1, performs the operations from S410 to S490, as shown in FIG. 8.

The system may perform the operation of meeting and merging, such as a part of S180 in FIG. 3, by performing the operations S410-S494. The system may manage negotiation of a meeting place between two groups by performing operations of S410-S494.

At S410, a facilitating section, such as the facilitating section 212, may first receive a suggestion of the meeting place from a representative mobile device of one group (which may hereinafter be referred to as “first group”) among the at least two groups. In one embodiment, if/when members of the first group may wish to join another group (which may hereinafter be referred to as “second group”) and travel to the target location with the second group, the representative mobile device of the first group may input a suggestion of meeting with the second group including a suggested meeting place, from its user. The representative mobile device may transmit the suggestion to the facilitating section of the server.

Next, at S420, the facilitating section may determine whether the second group is on the way to a meeting place with another group, or is having a negotiation of a meeting with another group. In one embodiment, if the facilitating section has already received a suggestion of meeting with the second group from another group and the suggestion has not been accepted nor rejected by the second group, then the facilitating section may determine that the second group has a pending negotiation. If the second group has accepted the suggestion from another group and is on the way to the meeting place with the another group, then the facilitating section may determine that the second group has a pending meeting.

If the second group has a pending meeting, then the facilitating section may proceed with S430. If the second group has a pending negotiation, then the facilitating section may wait for a certain time, and then proceed with S430. If the second group does not have a pending meeting or negotiation, then the facilitating section may proceed with S450.

At S430, the facilitating section may determine whether the second group has rejected the pending negotiation. In one embodiment, the facilitating section may receive the rejection from the second group as to the pending negotiation. In such a case, the facilitating section may determine that the second group has rejected the pending negotiation.

If the second group has rejected the pending negotiation, then the facilitating section may proceed with S450, and if not, then the facilitating section may end the operation of meeting and merging. If the second group has the pending meeting, the facilitating section may end the operation of meeting and merging.

At S450, the facilitating section may estimate a time of meeting of the first group and the second group, based on the suggestion from the first group.

In one embodiment, the facilitating section may determine a reasonable route (e.g., the shortest route) between a location of the first group and the suggested meeting place by a known algorithm (e.g., Dijkstra's Algorithm), and calculate a total length of the route. The facilitating section may calculate an amount of time for the first group to arrive at the suggested meeting place by dividing the total length of the route by a usual walking speed (e.g., 4 km/hour), and adding the amount of time to the current time to obtain a first time at which the first group arrives at the suggested meeting place.

Similarly, the facilitating section may estimate a second time at which the second group arrives at the suggested meeting place. The facilitating section may compare the first time and the second time, and determine the later one as the suggested meeting time of the first group and the second group.

At S455, the facilitating section may confirm whether to send the suggestion to the second group. In one embodiment, the facilitating section may send, to the representative mobile device of the first group, a message of confirmation of whether to send the suggestion of meeting at the suggested meeting place on the estimated time of meeting to the second group.

The facilitating section may receive a response from the representative mobile device of the first device. In one embodiment, the facilitating section may receive the response of “OK”, “Postponing the meeting time”, or “Changing suggestion.” If the response is “OK”, then the facilitating section may proceed with S460. If the response is “Postponing the meeting time”, then the facilitating section may receive a new meeting time from the representative mobile device, update the suggested meeting time with the new meeting time, and proceed with S460. If the response is “Changing suggestion”, then the facilitating section may go back to the operation of S410.

At S460, the facilitating section may transmit the suggestion to at least a second group among the at least two groups. In one embodiment, the facilitating section may transmit the suggestion from the first group to a representative mobile device of the second group. The facilitating section may transmit the suggestion including the suggested meeting place, and the meeting time estimated at S450 or updated at S455.

The representative mobile device of the second group may show the suggestion and the estimated time on the display screen, and input the response to the suggestion from the user.

Next, at S470, the facilitating section may receive the response to the suggestion of the first group from the second group. In one embodiment, the facilitating section may receive an agreement to the suggestion of the first group, a denial to the suggestion of the first group, or a counter suggestion of the meeting place, from the representative mobile device of the second group.

Next, at S490, if the facilitating section receives the agreement at S470, then the facilitating section may proceed with an operation of S492. If the facilitating section receives the denial at S470, then the facilitating section may proceed with an operation of S494.

If the facilitating section receives the counter suggestion at S470, then the facilitating section may go back to S450. In this case, the facilitating section may treat the counter suggestion from the second group as a new suggestion received at S410, and at S460, the facilitating section may transmit the counter suggestion to the representative mobile device of the first group.

At S492, the facilitating section may transmit the response to the suggestion of the first group from the second group, to the first group. In one embodiment, the facilitating section may transmit the agreement from the representative mobile device of the second group, to the representative mobile device of the first group. The facilitating section may go to “a” which is explained in relation to FIG. 14.

At S494, the facilitating section may transmit the response to the suggestion of the first group from the second group, to the first group. In one embodiment, the facilitating section may transmit the denial from the representative mobile device of the second group, to the representative mobile device of the first group. The facilitating section may end the operation of meeting and merging.

FIG. 9 shows an example of a display of the representative mobile device of the first group. The representative mobile device of the first group may input a meeting place from the user (or the leader of the first group), and show the input place on the display screen at S410. A circle 310 may represent place on a map that the representative mobile device of Group A (322) inputs as the suggested meeting place at S410. In one embodiment, the user may input the place by a touch screen. It must also be appreciated that groups B and C are represented by circles 324 and 320 respectively.

FIG. 10 shows an example of a display of the representative mobile device of the second group. The representative mobile device of the second group may show a message “Receives an offer to meet at the pointed place at 6:40 PM” (344B) as shown in FIG. 10 at S460 and input response from the user. In one embodiment, the representative mobile device of the second group may show the meeting place suggested by the first group by the circle 310B. The representative mobile device may input a response to the suggestion among “Accept Offer” (342), “Reject Offer” (341), and “Counter Offer” (343) on the display screen. The user of the mobile device may input response by tapping the “Accept Offer” icon corresponding to the agreement, the “Reject Offer” icon corresponding to the denial, or the “Counter Offer” icon corresponding to the counter suggestion. It must also be appreciated that groups A and B are represented by circles 324B and 320B respectively.

FIG. 11 shows an example of a display of the representative mobile device of the first group. If the facilitating section transmits the agreement to the representative mobile device of the first group at S492, then the representative mobile device may show a message to start navigation as shown in FIG. 11. It must also be appreciated that groups A and B are represented by circles 324C and 322C respectively.

The representative mobile devices of the first group and the second group may show a “Start Navigation” button (button 352) on the display screen. If the users of the representative mobile devices tap the “Start Navigation” button, then the representative mobile devices may display navigation information to the meeting place represented by the circle 310.

In one embodiment, the representative mobile devices may transmit a request of the navigation information to the server, and the server may generate and transmit the navigation information to the representative mobile devices. In other embodiment, the representative mobile devices of the first group and the second group may each generate the navigation information. The navigation information may include recommended route to the meeting place, and may be generated by the facilitating section such as navigation information 353.

FIG. 12 shows an example of a display of the representative mobile device of the second group. If the representative mobile device of the second group selects “Counter Offer” (343B) after receiving the suggestion from the first group at S460, the representative mobile device of the second group may show a message to select alternate meeting place as shown in FIG. 12 (by boxes 341B, 342B and 343B). It must also be appreciated that group B is shown here with circle 330.

In one embodiment, the representative mobile device of the second group may show a message “Offering an alternate place” (354) on the display screen, and input an alternate meeting place from the user (or the leader of the second group) by tapping of the display screen. The representative mobile device of the second group may show the input alternative meeting place on the display screen as shown by a circle 312. The representative mobile device of the second group may also show the place previously suggested by the first group in a less represented manner as shown by the dot circle 310.

FIG. 13 shows an example of a display of the representative mobile device of the first group. If the facilitating section transmits “Counter Offer” (344C) to the representative mobile device of the first group at S460 via S490, the representative mobile device of the first group may show a message to select a response to the counter offer as shown in FIG. 13. The representative mobile device of the first group may input a response to the suggestion among “Accept Offer” (342C), “Reject Offer” (341C), and “Counter Offer” (343C) on the display screen in a similar manner explained relating to FIG. 10.

FIG. 14 shows an example operational flow of the system according to an embodiment of the present disclosure. The present embodiment describes an example in which a system, such as the system 1, performs the operations from S510 to S590, as shown in FIG. 14. The system may perform the operations of S510-S590 after “a” of the flow in FIG. 8.

At S510, the collecting section may collect locations of the mobile devices. The collecting section may perform S510 in the same manner with S310. The collecting section may not perform S510, and use the locations of the mobile devices obtained at S310.

Next at S530, the identifying section may determine whether the meeting of the first group and the second group is completed. In one embodiment, the identifying section may determine the locations of the first group and the second group, and determine whether the locations are within a certain distance. In other embodiments, the identifying section may determine whether a certain number/ratio of members of the first group and the second group are located within a circle having a certain radius. In other embodiments, the identifying section may determine whether the representative mobile devices of the first group and the second group are located within a certain distance.

If determining that the meeting of the first and second groups is completed, the identifying section may proceed with S590. If determining that the meeting is not completed, the identifying section may proceed with S540.

At S540, a calculating section such as the calculating section 230 may calculate moving speed of the first group and moving speed of the second group. In one embodiment, the calculating section may calculate moving speed of a group based on speeds of median points of the group that move faster than a threshold speed. Thereby, the calculating section may reduce noise from the estimated speed.

Next, at S550, an estimating section such as the estimating section 232 may update the time that the at least two groups will meet at the meeting place based on the moving speeds of the at least two groups. In one embodiment, the estimating section may estimate the meeting time when the first group and the second group meets based on the moving speed estimated at S540, the location of the first group and the location of the second group. The estimating section may estimate the meeting time in a similar manner to the operation of S450.

The estimating section may transmit the estimated meeting time to the mobile devices of the first group and the second group. The mobile devices of the first group and the second group may display the updated meeting time on the display screen.

Next, at S560, the facilitating section may determine whether to receive cancel of the meeting from the representative mobile device of the first group or the second group. The representative mobile device of the first group and/or the second group may input cancel of the meeting from the user (e.g., the leader of the first/second group), before the first group and the second group meet, and may transmit the cancel of the meeting to the facilitating section.

If the facilitating section receives the cancel of the meeting, then the facilitating section may proceed with S580, and if not, the facilitating section may proceed with S565.

At S565, the facilitating section may determine whether to receive modification to the meeting from the representative mobile device of the first group or the second group. The representative mobile device of the first group and/or the second group may input modification to the meeting (e.g., changing a meeting place, and/or, meeting time) from the user (e.g., the leader of the first/second group), before the first group and the second group meet, and may transmit the modification to the meeting to the facilitating section.

If the facilitating section receives the modification to the meeting, then the facilitating section may go to “b” which is processed before S450 in FIG. 8, and if not, the facilitating section may proceed with S570. After going to “b”, the facilitating section may treat the modification to the meeting as a new suggestion received at S410 and proceed with the operation of S450 and further operations.

Next, at S570, the facilitating section may determine whether to receive the suggestion of meeting for the first group or the second group from the other group. If the facilitating section receives the suggestion from the representative mobile device of the other group, the facilitating section may proceed with S575. If the facilitating section does not receive the suggestion from the other group, the facilitating section may go back to the operation of S510.

At S575, the facilitating section may transmit the suggestion from the representative mobile device of the other group, to the representative mobile device of an object group. In one embodiment, if the facilitating section receives the suggestion of meeting to the first group from a third group at S570, the facilitating section may transmit the suggestion to the first group. At S575, the facilitating section may transmit the meeting place of the objective group (e.g., the first group) to the other group (e.g., the third group).

At S580, the facilitating section may cancel the current meeting of the objective group (e.g., the first group) and end the operation of S180.

At S590, a determining section such as the determining section 240 may determine a new representative mobile device among representative mobile devices of the first group and the second group. In one embodiment, the determining section may determine the new representative mobile device based on the numbers of mobile devices of the first group and the second group. In the embodiment, the determining section may determine the representative mobile device of the group that has larger number of mobile devices in the group as the new representative mobile device.

In one embodiment, the determining section may determine the new representative mobile device based on which group of the at least two groups suggested a meeting. In the embodiment, the determining section may determine the representative mobile device that has first sent the suggestion to the other group as the new representative mobile device.

A merging section such as the merging section 214 may update the information stored in the storing section to reflect the meeting of the first group and the second group. In one embodiment, the merging section may process a merger of the first group and the second group. In the embodiment, the merging section may update information of the group in the device ID list of the mobile devices to replace a merged group (e.g., a group received the suggestion) with a merging group (e.g., a group transmitting the suggestion), and to update information of the representative mobile device in the device ID list.

In one embodiment, the determining section may determine the new representative mobile device of the new group based on locations of mobile devices of the new group. In the embodiment, the determining section may determine one mobile device that is the closest to a center location of the new merged group as the new representative mobile device.

In one embodiment, after the first group and the second group have met, the first group and the second group may not be merged. In the embodiment, the first group and the second group may move together to the target location.

FIG. 15 illustrated a chart 1501 which is a graphical representation of average moving speed of a group. One group (e.g., the first group 1502), may move to the meeting place according to the average moving speed shown in FIG. 15. The calculating section may calculate the average moving speed of a group for a plurality of duration (e.g., 10 min). The calculating section may calculate average speed for a certain duration by calculating distance (direct distance or pathway distance) between a location of the group at the beginning of the duration and a location of the group at the end of the duration, and dividing the distance by the duration.

At S540 in FIG. 14, the calculating section may calculate moving speed of a group based on the average speed shown in FIG. 15. In one embodiment, the calculating section may calculate moving speed of a group based on the latest 60 min average speed of the group as indicated by a box 440. The latest 60 min corresponds 80-140 min on the graph of FIG. 15. Here, the calculating section may calculate moving speed of the group using average speed equal or above a threshold such as threshold 1503 (1 km/hour), which corresponds to average speed at 110-140 min, without using average speed below the threshold, which corresponds to average speed at 80-100 min.

FIG. 16 shows a display of the representative mobile device of the first group during the navigation. At S550 of FIG. 14, the mobile devices of the first group and the second group may show the updated meeting time estimated by the estimating section. In one embodiment, the representative mobile device of the first group may show a navigated route to the meeting place 310 and the updated meeting time on the display screen such as display 1604. It must be mentioned that like many other embodiments of the user interface options for modification 1602 and cancel 1603 are displayed.

FIG. 17 shows a display of the representative mobile device of the first group during the navigation. At S575 of FIG. 17, the representative mobile devices of the object group (e.g., the first group) may receive the suggestion from the other group from the facilitating section, and show a message on the display screen to notify a reception of the new suggestion as shown in FIG. 17 such as display 1704 or 1705. After reviewing the message, the user of the representative mobile device may cancel (1703) the current meeting to accept the new suggestion instead of the current meeting (modification 1702).

In one embodiment, the system may automatically create groups and start a session. For example, the server may detect a crowd of people from a variety of sensors, presume a reason that the people gather based on posts to SNS. The setting section may select an appropriate group policy based on a characteristic of the people (e.g., the reason of gathering), register mobile devices of the people as temporary participants to the session, start a session, and start the session.

The creating section may send a message to register as participants to the session or a representative mobile device of a group to the mobile devices of the participants. The creating section may send messages to the representative mobile devices to encourage the representative mobile devices to form groups. The system may continue the operations such as S165-S190 until the end of the session.

The system and method described above are applicable to a variety of events. In one embodiment, the system and method may be applicable to a travel with a plurality of groups (e.g., family, classmate, colleagues etc.), a packaged tour, a public viewing, etc.

FIG. 18 shows an example of a computer 1900 in which the mobile devices 10 and the server 20, the operational flow of FIGS. 3, 4, 6, 8 and 14, and/or other embodiments of the claimed disclosure may be wholly or partly embodied.

The computer 1900 according to the present embodiment includes a CPU 2000, a RAM 2020, a graphics controller 2075, and a display apparatus 2080, which are mutually connected by a host controller 2082. The computer 1900 also includes input/output units such as a communication interface 2030, a hard disk drive 2040, and a DVD-ROM drive 2060, which are connected to the host controller 2082 via an input/output controller 2084. The computer also includes legacy input/output units such as a ROM 2010 and a keyboard 2050, which are connected to the input/output controller 2084 through an input/output chip 2070.

The host controller 2082 connects the RAM 2020 with the CPU 2000 and the graphics controller 2075, which access the RAM 2020 at a high transfer rate. The CPU 2000 operates according to programs stored in the ROM 2010 and the RAM 2020, thereby controlling each unit. The graphics controller 2075 obtains image data generated by the CPU 2000 on a frame buffer or the like provided in the RAM 2020, and causes the image data to be displayed on the display apparatus 2080. Alternatively, the graphics controller 2075 may contain therein a frame buffer or the like for storing image data generated by the CPU 2000.

The input/output controller 2084 connects the host controller 2082 with the communication interface 2030, the hard disk drive 2040, and the DVD-ROM drive 2060, which are relatively high-speed input/output units. The communication interface 2030 communicates with other electronic devices via a network such as network 2081. The hard disk drive 2040 stores programs and data used by the CPU 2000 within the computer 1900. The DVD-ROM drive 2060 reads the programs or the data from the DVD-ROM 2095, and provides the hard disk drive 2040 with the programs or the data via the RAM 2020.

The ROM 2010 and the keyboard 2050 and the input/output chip 2070, which are relatively low-speed input/output units, are connected to the input/output controller 2084. The ROM 2010 stores therein a boot program or the like executed by the computer 1900 at the time of activation, a program depending on the hardware of the computer 1900. The keyboard 2050 inputs text data or commands from a user, and may provide the hard disk drive 2040 with the text data or the commands via the RAM 2020. The input/output chip 2070 connects a keyboard 2050 to an input/output controller 2084, and may connect various input/output units via a parallel port, a serial port, a keyboard port, a mouse port, and the like to the input/output controller 2084.

A program to be stored on the hard disk drive 2040 via the RAM 2020 is provided by a recording medium as the DVD-ROM 2095, and an IC card. The program is read from the recording medium, installed into the hard disk drive 2040 within the computer 1900 via the RAM 2020, and executed in the CPU 2000.

A program that is installed in the computer 1900 may cause the computer 1900 to function as an apparatus, such as the mobile devices 10 and the server 20 of FIG. 1. The program or module acts on the CPU 2000, to cause the computer 1900 to function as some or all of the sections, components, elements, etc. of the mobile devices 10 and the server 20 of FIG. 1 (e.g., the setting section 202, the creating section 204, the storing section 206, the providing section 208, etc.).

A program that is installed in the computer 1900 can also cause the computer 1900 to perform an operational flow such as the operational flow of FIGS. 3, 4, 6, 8 and 14. Such a program may act on the CPU 2000 to cause the computer 1900 to perform some or all of the steps of FIGS. 3, 4, 6, 8 and 14.

The information processing described in these programs is read into the computer 1900 such as the server 20 of FIG. 1 function as each section (e.g., the setting section 202, the creating section 204, the storing section 206, the providing section 208), resulting in the cooperation between the program or module and the above-mentioned various types of hardware resources. An apparatus or method may be constituted by realizing the operation or processing of information in accordance with the usage of the computer 1900.

For example, in response to communication between the computer 1900 and an external device, the CPU 2000 may execute a communication program loaded onto the RAM 2020, to instruct communication processing to a communication interface 2030, based on the processing described in the communication program.

The communication interface 2030, under control of the CPU 2000, reads the transmission data stored on the transmission buffering region provided in the recording medium, such as a RAM 2020, a hard disk drive 2040, or a DVD-ROM 2095, and transmits the read transmission data to a network, or writes reception data received from a network to a reception buffering region or the like provided on the recording medium. In this way, the communication interface 2030 may exchange transmission/reception data with the recording medium by a DMA (direct memory access) method, or by a configuration that the CPU 2000 reads the data from the recording medium or the communication interface 2030 of a transfer destination, to write the data into the communication interface 2030 or the recording medium of the transfer destination, so as to transfer the transmission/reception data.

In addition, the CPU 2000 may cause all or a necessary portion of the file of the database to be read into the RAM 2020 such as by DMA transfer, the file or the database having been stored in an external recording medium such as the hard disk drive 2040, the DVD-ROM drive 2060 (DVD-ROM 2095) to perform various types of processing onto the data on the RAM 2020. The CPU 2000 may then write back the processed data to the external recording medium by means of a DMA transfer method or the like. In such processing, the RAM 2020 can be considered to temporarily store the contents of the external recording medium, and so the RAM 2020, the external recording apparatus, and the like are collectively referred to as a memory, a storage section, a recording medium, a computer readable medium, etc.

Various types of information, such as various types of programs, data, tables, and databases, may be stored in the recording apparatus, to undergo information processing. Note that the CPU 2000 may also use a part of the RAM 2020 to perform reading/writing thereto on the cache memory. In such an embodiment, the cache is considered to be contained in the RAM 2020, the memory, and/or the recording medium unless noted otherwise, since the cache memory performs part of the function of the RAM 2020.

The CPU 2000 may perform various types of processing, onto the data read from a memory such as the RAM 2020, which includes various types of operations, processing of information, condition judging, search/replace of information, etc., as described in the present embodiment and designated by an instruction sequence of programs, and writes the result back to the memory such as the RAM 2020. For example, if performing condition judging, then the CPU 2000 may judge whether each type of variable shown in the present embodiment is larger, smaller, no smaller than, no greater than, or equal to the other variable or constant, and if the condition judging results in the affirmative (or in the negative), then the process branches to a different instruction sequence, or calls a sub routine.

In addition, the CPU 2000 may search for information in a file, a database, etc., in the recording medium. For example, if a plurality of entries, each having an attribute value of a first attribute is associated with an attribute value of a second attribute, are stored in a recording apparatus, then the CPU 2000 may search for an entry matching the condition whose attribute value of the first attribute is designated, from among the plurality of entries stored in the recording medium, and reads the attribute value of the second attribute stored in the entry, thereby obtaining the attribute value of the second attribute associated with the first attribute satisfying the certain condition.

The above-explained program or module may be stored in an external recording medium. Exemplary recording mediums include a DVD-ROM 2095, as well as an optical recording medium such as a Blu-ray Disk or a CD, a magneto-optic recording medium such as a MO, a tape medium, and a semiconductor memory such as an IC card. In addition, a recording medium such as a hard disk or a RAM provided in a server system connected to a dedicated communication network or the Internet can be used as a recording medium, thereby providing the program to the computer 1900 via the network.

The present disclosure may be a system, a method, and/or a computer program product. The computer program product may include a computer readable storage medium (or media) having computer readable program instructions thereon for causing a processor to carry out aspects of the present disclosure.

The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device.
